About Universe Sandbox
Create, collide, and manipulate entire planetary systems in real-time using actual Newtonian physics to watch supernovas erupt, oceans boil, and worlds transform. Universe Sandbox stands out with its mind-bending scale and scientific accuracy, letting you terraform planets, trigger stellar catastrophes, and explore everything from historical space missions to black hole gravity wells without needing a supercomputer.
It merges real-time gravity, climate, collision, and material interactions to reveal the beauty of our universe and the fragility of our planet.
Simulate Gravity
N-body simulation at almost any speed using Newtonian mechanics. Real science, real physics, no supercomputer required.Collide Planets & Stars
Epic, mind blowing collisions of massive planetary bodies that leave behind molten craters.Create Your Own Systems
Start with a star, then add a planet. Spruce it up with moons, rings, comets, or even a black hole.Model Planetary Climate
Watch sea ice grow and recede with the seasons because of a planet’s tilt - change the tilt and change the seasons. Or move planets close to a star and see the oceans boil away as the surface heats up.Supernova a Star
Watch a supernova unfold by colliding two stars, cranking up their mass, or making them explode at your whim.Explore Historical Events
Hitch a ride with spacecraft including Juno and New Horizons, or view a total solar eclipse.And more...
